Abstract:

A novel polyoxometalate-based hybrid modified by 3d-4d/2-ptz heterometallic organic chains[n-ptz=5-(n-pyridyl)-tetrazolate], Ag2[Cu(2-ptz)2][β-Mo8O26]0.5·H2O(1)[2-ptz=5-(2-pyridyl)-tetrazolate], was synthesized under hydrothermal conditions. The 3D framework structure of compound 1 was constructed from 1D novel 3d-4d heterometallic organic chains[CuAg2(2-ptz)2]2+ as cationic complexes and[β-Mo8O26]4- polyoxoanions via Cu-O and Ag-O bonds, in which each[β-Mo8O26]4- polyoxoanion was surrounded by six such chains. The electrochemical and photocatalytic properties of compound 1 were investigated.

Key words: Polyoxometalate, Heterometallic organic chain, Crystal structure
